How do I Convert OST to PST – IMAP and Exchange

Share the post

Convert OST to PST: Microsoft Outlook is a great application when it comes to the ease of use and the looks of it and then combining it with Microsoft Exchange Server will surely make a great combination. With the default configuration of any account Outlook will keep an OST file as a synchronization between the local application and the server.

 

Why is an OST used

An OST file will come in handy when you want to be able to access your emails when you are not connected to the Exchange server or if the Exchange server is down. As said before Microsoft Outlook and Microsoft Exchange Server are a great combination and work perfectly with each other, unfortunately issues may arise which will affect the integrity of the local OST file on the user’s computer. A little note on this is that for you to have an OST file of your Exchange Server mailbox you will need to enable the Cached Exchange Mode enabled as if it’s unticked in the Account Setting you will connect directly to the server.

Of course if you untick the option, the experience of the user will be hindered as the performance of Outlook will be degraded and the user will not be able to see his email if he doesn’t have internet or connection to the Exchange Server.

Since Outlook leaves the OST file open all the time you will might encounter a number of issues with the OST is not opening with various culprits. When Outlook crashes and the file is open you might end up with an inaccessible OST file, during Office or Windows Updates. The OST can also be inaccessible due to a sudden power cut of the device or a fault in the device’s hardware, a virus infection or a heavy loaded antivirus which might hinder the integrity of the file.

When an Outlook OST file gets inaccessible you will end up with an Outlook which will not allow the use to load the application or to communicate with the Exchange Server. To be honest one can easily justify the fact you cannot connect as the solution would be to remove the profile from the Mail object in the Control Panel and re-create the user’s profile which will create a new OST file and re-synch all the data. The problem with this is you will resync all the mailbox and any work while offline will be lost since the OST file cannot be reused and you cannot open it. This means that if your local copy is lost you can re-sync the mailbox, but what if the server is lost?

Taking note of this if you have Microsoft Office 2013 upwards any IMAP accounts are setup using an OST file rather than a PST. Most ISPs who offer mailboxes mostly connect via IMAP. When using IMAP although with Outlook it will sync a copy of the mailbox on your device, if something happens to the server… there is no way to recover your data and everything will be lost. Although you still have the OST file on your local PC it will be unusable.

Another situation that personally I was in, is that I had a computer which had an old account synchronized which mailbox was removed. Till then no issue, but the computer went bust and although the hard drive was recoverable, I couldn’t use it in any way. Since the mailbox was removed ages ago, there was no way I could read the OST file.
